sTEAM-ENel- EQ SPECIFICATION forming part of Letters Patent No. 408,154, dated July 30, 1889. Application filed December 22, 1888. Serial No. 294,371- (No model.)

To all whom, it may concern:

Be it known that I, SILAS S. IYILLIAMS, a citizen of the United States, and a resident of East Randolph, in the county of Oattaraugus and State of New York, have invented certain new and useful Improvements in Steam-Engines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to steam-engines.

The object is to produce a steam-engine which shall be of such construction that the cylinders will be prevented from becoming loose upon their base by the vibratory motion imparted to them when the engine isrunning; furthermore, to produce an engine which shall be of the highest eflioiency in use and which may be constructed at a less expense than engines of ordinary construction.

lVith these objects in view the invention consists in the improved construction and combination of parts of a double-cylinderengine, as will be hereinafter fully described in the specification, illustrated in the drawings, and pointed out in the claims.

In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, Figure 1 is a perspective View showing two cylinders, the cross-head for connecting the piston-rods of the same, and the guides secured to the cylinder-heads for the crosshead to run upon, and a connecting-rod extending from the cross-head to the crank-shaft placed below the cylinders, and Fig. 2 is an end view of the same.

Referring to the drawings, A designates the base of the engine, which is constructed preferably of iron. 0n the upper side of this base are bolted two cylinders B, the space between the two being suiiicient to admit of a connecting-rod working between the same. To the top of the cylinders are secured the cylinder-heads C. To these are secured two guides 2, which are connected by means of a yoke 3, designed to hold them at the proper distance apart. To the piston-rods at is 0011- neeted a cross-head 5, which moves 011 the guides 2 of the cylinder-heads, thus doing away with the necessity of having additional guides built on the engine-frame for that purpose, as with engines of the ordinary construction. On the cross-head is mounted a connecting-rod 6, which passes down and through an opening 7, formed between the cylinders, and connects with a crank-shaft 8 below thesame. This shaft 8 is journaled in bearings formed in standards 10, secured to the under side of the base upon which the cylinders are mounted, the bolts 11, for holding the standards in place, passing through the base and into the flanges 12 of the cylinders, thus securely bolting the two together. Thus it will be seen that when the piston-rod is driven either up or down and revolves the crank-shaft the strain will be concentrated at one point-that is, all the strain of the crank-shaft will be transmitted through the standards to the under side of the base, and the strain from the piston-rod will be transmitted through the cylinders to the upper side of the base, thereby throwing all the strain and pressure upon the base and removing it from the cylinders, thus preventing the same from working loose,

It will thus be seen that although this engine is exceedingly simple of construction, it will be found highly efficient and durable in use, and may be constructed at but a slight expense.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a steam-engine, the combination of the base, the cylinders mounted thereon, having a flange on their lower ends, the standards below the base, bolts extending through the standards and engaging the flanges on the cylinder, a crank-shaft mounted in the standards, a cross-head, and a connecting-rod connecting the cross-head and crank-shaft, substantially as described.

2. In a steam-engine, the combination of the base, the cylinders mounted thereon, the guides secured to the cylinders, the cross-head mounted on the guides, and the piston-rods secured to the cross-head, substantially as described.

3. In a steam-engine, the combination of the base, the cylinders mounted thereon, the In testimony that I claim the foregoing as guides secured to the cylinders, the yoke oonmy own I have hereunto affixed my signature necting the guides, the cross-head mounted in presence of two Witnesses.
